Abstract
Bei einem digitalen Übertragungssystem mit einem Multi plexer/Demultiplexer, der eine Information für mehrere Kommunikationskanäle in eine Information für einzelne Informationskanäle oder eine Zusammenfassung von Infor mationskanälen aufteilt bzw. umgekehrt die Information von einzelnen Informationskanälen zusammenfaßt oder die Zusammenfassung von Informationskanälen zu einer gemeinsamen Information zusammenfaßt, weist der Multi plexer/Demultiplexer teilnehmerseits für jeden Teil nehmeranschluß eine Vierdraht-Schnittstelle auf, die für den Anschluß einer optischen Übertragungseinheit vorgesehen ist. In a digital transmission system with a multi plexer / demultiplexer that holds one piece of information for several Communication channels in information for individual Information channels or a summary of Infor distribution channels or vice versa the information summarized from individual information channels or the combination of information channels into one summarizes common information, shows the Multi Participant plexer / demultiplexer for each part slave connection to a four-wire interface for connecting an optical transmission unit is provided.
